skin contact; wash with soap and water in
case of spills.
The fuel filter must be replaced regularly, see
Maintenance schedule for intervals, or if the

1. Place a suitable container under the filter.
2. Clean the filter bracket and filter cartridge
externally with white spirit or diesel.
3. Blow dry with compressed air.
4. Clamp together the inlet hose with self-
locking pliers if the level in the tank is so
high that there is a risk of leakage.
5. Replace filter cartridge.

Servicing the air filter
If the engine seems to lack power or does not
run smoothly, the reason may be that the air
filter is clogged. When driving with a dirty air
filter the engine does not receive enough air,
which does not meet the environmental
demands, and the engine does not operate at
full efficiency.
